I have a few of these Jackpot Casino, Las Vegas, NV $1 chips with the EWING mold. Chips are in used condition. Many of these chips are found with the inlay damaged. I have some with no damage, good inlay on both sides, and some with a good inlay on one side only.

The Official U.S. Guide has these chips listed as $7-$14-$21.
In TCR9 these are N6819, "E" value, $15 to $19.
They are available for $4 each, one good inlay or $10 with both inlays good.
